A driver IC comprises a voltage detector configured to detect an input voltage to the driver IC, a charge pump configured to generate a regulator driving voltage by amplifying the input voltage and output the regulator driving voltage, a regulator configured to receive the regulator driving voltage and output a regulator voltage, a gamma circuit configured to generate a gray scale voltage using the regulator voltage, and a voltage controller configured to generate a command signal corresponding to the input voltage. An OLED display comprises a pixel unit configured to display an image in response to a data signal, a scan signal, a light emitting control signal, first and second voltages, the driver IC, a scan driving unit, and a power supply unit configured to adjust levels of the first and second voltages in response to the input voltage, and transmit the first and second voltages to the pixel unit.
